With a storied history beginning with the establishment of the modern-era Pops by Arthur Fiedler and continuing through to the new millennium under the direction of Keith Lockhart, the Boston Pops Esplanade Orchestra is among the most beloved symphonic ensembles in the country. Often called “America’s Orchestra,” the group comes to the Greek to celebrate the extraordinary five-decade career of one of its former conductors, 22-time Grammy winner John Williams. The program includes selections from some of Williams’ most iconic Hollywood film scores, including music from Star Wars, Jaws, E.T., and the Indiana Jones and Harry Potter films.
